[request #48542] addition of optional second parameter to array_shift/array_pop which gives key

Hi there, I saw this bug report (feature request): https://bugs.php.net/bug.php?id=48542 The person there proposes that array_shift and array_pop should have an optional second parameter, which can be passed a reference to a variable in which the key can be returned, so you can pop the key and value at the same time, rather than having to get the key first, then pop the pair to get the value. Thoughts? I'm new to PHP development, I thought this might be a useful feature that I could relatively easily implement. Also, I can personally see how this could be useful having used arrays as essentially look-up tables before. -- Andrew Faulds (AJF) http://ajf.me/
